Professor's 'Arrow of Time' brings some understanding about the world's dilemmas

A discussion about the origin of the universe and the “Arrow of Time” helped explain much about dilemmas presently troubling the world.

The California Institute of Technology’s Prof Sean Carroll (right), from the institute’s Department of Physics, recently expanded on his ideas to an over-flowing auditorium at the Elisabeth Murdoch Building at the University of Melbourne.
His discussion was not about resolving, or discussing, the world’s difficulties, but as he spoke to the riveted crowd those complexities, at least for me, became a little more understandable.
Explaining our 14 billion-year-old universe, Prof Carroll discussed entropy, which, he said, will, according the second law of thermodynamics, increase in an isolated system. Our universe is an isolated system
Measurable and understandable physics indicate that disorder and entropy was low when the universe first took shape, but all these years later, and it just happens to be “our” time, both are increasing to a point where they are threatening to escape our understanding and let loose on the world largely unknown happenings.
What’s evolving, it’s important to note, is not a response by any supernatural being reacting to human behaviour, rather it is a predictable and physical eventuality that is being hurried somewhat by the sheer number of humans who seem obsessed about rushing closer to the precipice.
Our world, which is an isolated system in its own right, is subject to the same dynamics and we are struggling with the resultant entropy.
Sadly we rush about dealing endlessly with the manifestations of that entropy believing them to be the doings of some super-natural being or some sinister other, rather than the expansion of our universe and so galaxy simply doing what it is they do.
Being thinking and doing organisms, we have mistakenly elevated ourselves to a pre-eminent position on our planet and have done that without much thought about tomorrow.
Our time here, in a geological sense, will be brief, but with a thoughtful approach to how we should live, we can employ entropy to our advantage.
As with aging it is about slowing down and disorder, and so considering that, we should aim at living more restrained lives.
